<h3>Answer:  45.7 degrees (choice A)</h3>

=======================================================

Explanation:

Apply the tangent ratio and inverse tangent function (aka arctangent) to get the following

tan(angle) = opposite/adjacent

tan(x) = 8/7.8

x = arctan(8/7.8)

x = 45.7252242990592

x = 45.7

Be sure that your calculator is in degree mode.
